I have been reading up on body pieces as the ole FJ40 needs some serious TLC in that department. I have found steel, aluminum and fiberglass replacement fenders both in stock size or about 3" wider than stock. I like the idea of fiberglass, but don't like the thought when I bang it against a rock or a tree and it looks like the front end of a Vette after a fender bender. So, how about aluminum? I have read opinions that state that there is a corrosion factor due to aluminum/steel contact and others that say that this poses no significant problem. On the other hand, Al will not rust and that is a very good thing. What are your opinions on which way to go? How much difference is there in strength and weight? Do you think I should run the wider fenders because 35x12.5 stick out a few inches past the stock ones?
